ABSTRACT:
In hydrodynamic bearings it is necessary for the lubricant leaving the lubricant film to be cooled. The self-sufficient, reliable operation of the system is only ensured if the transport of lubricant can be generated and maintained by the bearing itself. For this purpose the lubricant is taken from the contact surface of the moving component (2) into a pumping gap (13), recessed in the stationary component (4), which exhibits a strong constriction (17) in the direction of movement by a graduation (16). This pumping gap (13) may be machined directly in the contact surface of a bearing segment or in a separate component. A part of the lubricant stream which enters the pumping gap (13) is removed in front of the constriction (17) through an appropriate lubricant discharge duct (14). This branched lubricant stream (19) represents the delivery quantity of the pumping gap (13). The remainder of the branched lubricant stream flows on through the lubrication gap (18). The pumping pressure corresponds to the pressure built up hydrodynamically in the pumping gap (13).
